The NPN-type triode has the characteristic that the base electrode inputs high level and then is conducted, so that when the base electrode of the first NPN-type triode Q1 inputs a high-level temperature detection signal, the first NPN-type triode Q1 is conducted, and at the moment, the relay KM1 is electrified and sends an excitation signal to enable a contact KM1-1 of the relay to be closed. At this moment, the oscillator is electrified and outputs an oscillating signal, when the oscillating signal is at a high level, the second NPN triode Q2 is conducted to enable the buzzer HA to be electrified and make a sound, when the oscillating signal is at a low level, the second NPN triode Q2 is cut off to enable the buzzer HA to be powered off and turned off, so that the buzzer HA emits continuous short sounds, thereby warning maintenance personnel, facilitating the maintenance personnel to check and maintain the cabinet in time, reducing potential safety hazards, and avoiding burning out parts in the cabinet body 1 due to overheating.
The implementation principle of the embodiment is as follows: when parts on the interlayer 25 need to be maintained, a maintenance person only needs to rotate the interlayer 25 around the main shaft 2 to the position opposite to the maintenance person, so that the parts are convenient to maintain, and meanwhile, when the interlayer 25 rotates, wires connected to the parts rotate along with the parts.
When the wiring terminal rotates along with the interlayer 25, the wire is pulled, and the wire drives the wire clamping device 33 to slide, so that the length of the wire required by the rotation compensation of the interlayer 25 is compensated, the rotation of the interlayer 25 is realized, the maintenance difficulty is reduced, and the maintenance efficiency is improved.
When the interlayer 25 is required to be rotated greatly so that the failed part faces to a maintainer, the maintainer only needs to separate the terminal ring 31 into the socket part 311 and the bearing part 312, so that the wire penetrating out of the threading cavity 22 is separated from the wire connected with the part, the interlayer 25 can be rotated freely conveniently, the wire is prevented from being broken due to the tension influence of the wire, the wire is protected, the interlayer 25 is rotated greatly, the maintenance difficulty is reduced, and the maintenance efficiency is improved.
Embodiment two: referring to fig. 6, a rotatable rack with an interlayer is different from the first embodiment in that: the supporting rod 21 is provided with a driving motor 34, the driving motor 34 is fixed with the supporting rod 21 through a screw, and an output shaft of the driving motor is coaxially fixed with the screw 32.
The implementation principle of the embodiment is as follows: when it is desired to rotate the interlayer 2525 substantially to orient the failed part to the service personnel, the service personnel need only activate the drive motor 34. At this time, the driving motor 34 drives the screw 32 to rotate, and the screw 32 drives the bearing part 312 to be far away from the socket part 311, so that the wires penetrating out of the main shaft 2 and the wires on the parts can be conveniently separated, manual operation is reduced, maintenance personnel can conveniently maintain the parts, potential safety hazards such as electric shock are reduced, and safety is improved.
The embodiments of the present invention are all preferred embodiments of the present invention, and are not intended to limit the scope of the present invention in this way, therefore: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
